I've been working on a sourdough starter for almost 3 weeks and I can't seem to get any rise out of it. I feel like I've tried every trick I've read online and nothing has worked.
I started with wheat flour and then switched to white after the first feeding. After a few days of measuring with cups I've since been measuring by weight. I had some hooch early on (maybe day 3-5?) but only small amount, if any, since. I get a varying level of bubbles but no rise. I've done the float test and failed. I've tried everything...feeding every 12 hours, feeding every 24 hours, doing one feeding with wheat flour, feeding 1:2:2, feeding 1:1:1, you name it. I've tried keeping it in a pyrex bowl with a towel on it, pyrex bowl with lid, in a mason jar with saran wrap, mason jar with lid tight, etc. I tried each of these for a few days before modifying.
The only thing that seems to have gotten any rise was when I put it in the microwave with a cup of hot water - I've done this twice and the 1st time I got some decent rise out of it, the 2nd time nothing really. I live in Florida and its very hot/humid so temp shouldn't be the issue.
Consistency is normally very thick after I feed but when it comes time to the next feeding its very runny and thin.
Does anyone have any tips on what else I should do? Am I just trying too many things? HELP!
